it seems when we create a new dive and then go to the favorite sites in order to edit them, all new divers are checked as favorites; I would prefer to have every new dive not favorite and check the one I want (if go for a trip of 20 dives, most of the time, 2 or 3 are part of the favorites, not all of them

A lot of divers also go on the occasional snorkel trip, or snorkel between dives. I'm one of them and have lots of photos I'd love to share, particularly of spots that are also good dive spots. There should be an option to share a snorkel spot, or a way to add photos to a dive spot without adding it as a "dive." :)
